Abstract:
The utility model relates to an earphone with air release valve, comprising a shell, the shell is provided with an earphone rear cavity for accommodating a sounding unit, the sounding unit is placed in the earphone rear cavity and fixedly connected with the shell, the side of the shell facing the human ear is connected with an ear pad, the earphone is provided with an air release hole on the earphone shell between the earphone rear cavity and the earphone sound chamber cavity, and the air release hole is provided with an air release valve which automatically opens due to the increase of pressure. Therefore, when the people wear the earphone or transmit the earphone, the instantaneous pressure wave produced in the sound chamber cavity can be discharged from the air release valve. As for the earphone of the utility model, the vibrating diaphragm is less affected by the airflow interference such that the earphone is characterized by higher sound purity and better hearing experience compared with those earphones only having the air release hole rather than the valve.
